Abstract

Abstract

The resistance and thickness of distributed-loss circuit of gyrotron traveling wave amplifier are optimized by using the multi-objective genetic algorithm. Maximum gain of 15.9 dB is obtained by optimizing the thickness and resistivity of loss layer as 0.116 mm and 77 882 times the resistivity of copper, respectively. The accuracy is verified by the single-objective genetic algorithm, which makes the amplifier realize effective restraint of gyrotron backward wave oscillation and achieve the maximum gain.
